_Treatment._ In the treatment of this form of gastritis the first consideration is to expel, or use an antidote to, the poison. In the soliped, emetics are useless. The stomach pump or tube may, however, be applied with good effect in nearly all cases, alternately throwing in water and drawing it off. Demulcents and coagulants are also universally applicable. Milk, eggs beaten up in milk, blood albumen, flaxseed tea, well boiled gruels, or slippery elm bark, may be used as may be most convenient. Next come the other chemical antidotes the use of which however demands a previous knowledge of the poison present. For the mineral acids one can make use of calcined magnesia, lime water, chalk, or carbonate of soda in weak solution. For alkalies the appropriate antidote is vinegar. For carbolic acid, vinegar, alcohol, or failing these a weak solution of soda or oil. For tartar emetic, gallic or tannic acid. For bichromate of potash or chromic acid, calcined magnesia, magnesia carbonate, or lime carbonate. For phosphorus, old oil of turpentine and demulcents—no oil. For ammonia, vinegar followed by almond, olive or sweet oil. In case of œdema glottidis, tracheotomy. For copper salts yellow prussiate of potash, which precipitates the copper in an insoluble form, and demulcents. For mercuric chloride, demulcent drinks can be resorted to, there is no other reliable antidote. In all cases after the evacuation of the stomach and the use of the antidote, mucilaginous agents must be given freely with morphia or other anodynes. CATARRHAL INFLAMMATION OF THE FOURTH STOMACH. Usually a complication. Causes, predisposing, exciting, changes of food or water, spoiled, frosted or fermented food, green potatoes, caterpillars, nitrogenous food, irritants. Symptoms: Separation from herd, grinding teeth, eructation, depraved appetite, fever, tender epigastrium, coated dung, red eyes, fixed or retracted, dilated, blind eyes, drooping ears, nervous symptoms, reckless unconscious movements, bellowing, tender skin, tremors. Lesions: Congestion and exudate in gastric mucosa, hemorrhagic discoloration, desquamation, excess of mucus, resemblance to rinderpest, Texas fever and malignant catarrh. Treatment: Empty stomach by bland laxatives, stimulants of peristalsis, calmatives, cold to head, counter-irritants, enemata, bitters. This affection is by no means rare in cattle, though it is usually complicated with inflammation of the first three stomachs or of the intestines. Nevertheless, when the disease appears to be concentrated on the fourth stomach mainly, it may well take its name accordingly.
